The Sonographic Murphy sign is an ultrasound finding used primarily in the diagnosis of acute cholecystitis, which is inflammation of the gallbladder, usually due to gallstones. During ultrasound examination of the gallbladder, the Sonographic Murphy sign is elicited by applying pressure with the ultrasound transducer over the gallbladder area. If the patient experiences pain or tenderness in response to this pressure, it is considered a positive Murphy sign.
Ultrasound energy refers to sound waves that have frequencies higher than the upper limit of human hearing, typically above 20 kHz. While humans can hear sounds ranging from about 20 Hz to 20 kHz, ultrasound is utilized in various fields due to its unique properties and capabilities.
Laser capture microdissection (LCM) is a sophisticated technique used to isolate and analyze specific cells from heterogeneous tissue samples based on their morphology. It allows researchers to capture single cells or groups of cells with spatial precision, enabling the study of cellular and molecular characteristics in a targeted manner. ### Key Features of Laser Capture Microdissection: 1. **Precision**: LCM uses a laser to precisely cut and remove desired cells from a tissue section.
Laser lithotripsy is a medical procedure used to break up kidney stones or urinary tract stones using a laser. The technique is generally performed during a procedure called ureteroscopy, where a thin, flexible tube (ureteroscope) is inserted into the urethra, through the bladder, and into the ureter or kidney. Here's how the procedure works: 1. **Preparation**: The patient is usually given anesthesia and positioned comfortably.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
